The scattered showers -- which dumped about 1 inch in downtown Los Angeles and half an inch in Glendale -- prompted the National Weather Service to issue a flood advisory for the whole L.A. Basin, including Glendale and Burbank.

The interchange for the 405 and 710 freeways in Long Beach had slower-than-usual traffic because of the heavy rains, according to the weather service.

In Boyle Heights, a clogged drain caused minor flooding along the 500 block of Bernal Avene, and firefighters were dispatched to the area to unclog the drains, according to LAFD spokeswoman Margaret Stewart.
